Sub-bottom profiler and side scan sonar EdgeTech 2000-DSS

This equipment is designed for geologic and geophysical explorations: cable and pipework searching, survey of sea constructions and bottom before and after dredging.



The main feature of EdgeTech 2000-DSS is combination of a frequency-modulated dual frequency side scan sonar and high-resolution sub-bottom profiler in one fully integrated system. There is an interface for connecting magnetometer SeaSPY. The set uses CHIRP (Compressed High Intensity Radar Pulse) – a full-specter technology that allows to increase signal/noise rate and essentially increase resolution of imagery got with the sub-bottom profiler and side scan sonar.
